' RAILWAY-TIE.

SPECIFICATION forming part of Letters Application filed August 28, 1883.(No model.)

.To all whom, t may concern:

Be it known that I, JAMES J. DU BOIs, a citizen of the UnitedStates, anda resident of Springtown, in the county of Ulster and State of N ewYork, have invented certain new and useful Improvements inRailway-Ties;. and I do hereby declare th at the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and-use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- A Figure l is a plan or top view of aportion of a railway-track laid upon my improved ties. Fig. 2is aperspective `view of one of the ties removed from the track; and Fig. 3is a vertical cross-section through line x a: in Fig. l.

Similar letters of referenceindicate corresponding parts in all thefigures.

My invention has relation to the construction of railway-tracks orpermanent ways; and

it consists in an improved construction of the ties or sleepers whichsupport the rails, as hereinafter more fully describedfand claimed. Inthe accompanying drawings, A denotes .the rails of a railway-track, andB the ties.

The latter'are madeof metal, or other suitable material. possessing therequisite degree of strength and durability, each tie being recessed atopposite ends to form the rail-chairs C, which are provided with thelocking-blocks or rail-seats D, for locking the rail firmly in itsposition in the chair. These locking-blocks D are made of such a shapeas to be rhomboidal in section, as clearly shown in the drawings, andare fastened upon the 4body of theV ties, after being placed in positionin the rail-chair, by means of bolts E and nuts F, the bolts beinginserted through the ties from their under side, and the nuts beingscrewed down against the side of the blocks D. By referenceto Fig.

l ofthe drawings it will be seen that these holding-blocksv are disposedalternately on oppo- Patent No. 292,421, dated January 22, 1854.

this arrangement of the rail-chairs and their blocks I greatlyfacilitate both laying and removing of the track, and also eftectuallyprevent spreading of the rails. Another advanexact gage for the track,so that no spacing is necessary, as the rails are bound to be the properdistance apart simply by placing them in their appropriate chairs inopposite ends of the ties.

It will be seen that by constructing the locking-block D of the shapedescribed and shown, when that edge of the said block which bearsagainst the rail becomes worn through use, the block may be turned orreversed, so as to present a new and unworn edge to bear against therail, by which arrangement alocking-block of my improved constructionwill re= main serviceable twice as long as one not so constructed. Y

I am aware that rail road-ties have been heretofore constructedcomprising a locking-block adapted to be slid or forced into the spacebetween one side of the rail-chair and the side of the rail, and held inthat position by means of a suitable bolt; and I do not therefore claimsuch construction, broadly; but I What I claim as my invention, anddesire to secure by Letters Patent of the United States, 1s-

The combination of the tie B, provided with the rail-chairs C, thereversible rhomboidal lockingeblocks D, and meansby which the saidblocks are secured in their operative position, as set forth.

In testimony that I claim the .foregoing as my own I have hereuntoafliXed my's'ignature in presence of two witnesses.
